Application of seawater direct current cooling circulation water system tidal range influence model

Abstract

The invention relates to the application of a seawater direct current cooling circulation water system tidal range influence model. The circulation water system tidal range influence model is established through the analysis treatment of the tidal level and circulation water system characteristic data, the circulation water system characteristics of the target operation mode under the lowest tidal level can be predicted through the application of the circulation water system tidal range influence model, an equipment security strategy is combined to guide the safe operation of equipment, meanwhile the optimization is performed on the current circulation water system operation condition through the application of the established circulation water system tidal range influence model, and accordingly the accuracy of the optimization calculation can be improved.

Description

technical field [0001] The invention relates to the application of a tidal range influence model of a seawater direct cooling circulating water system. [0002] Background technique [0003] The existing circulating water system performance test program is to directly measure the characteristic data of the circulating water system, such as inlet pressure, inlet temperature, outlet pressure, outlet temperature, system water flow and circulating water system motor power under a certain operating mode. The data are fitted and calculated to obtain the inherent performance characteristics of the circulating water system. The inherent performance characteristics of the circulating water system are combined with the condenser characteristic curve family and the steam turbine vacuum micro-increasing characteristics to optimize the equipment operation of the circulating water system, so as to obtain the optimization of the circulating water system under the current unit load and cir...

Problems solved by technology

The data measured by the existing test technology is the coupling data of the inherent performance characteristics of the circulating water system and the influence of seawater tide level factors on the characteristics of the circulating water system, and the tide level of seawater is a regular change process, so the obtained during the test As a result, it can only represent the characteristics of the circulating water system at a fixed tidal level, and cannot effectively represent the inherent performance characteristics of the circulating water system, resulting in the calculation results of the performance characteristics of the circulating water system being affected by the tidal level factor and deviating from the actual value. This part is not considered Influencing factors will affect the safe operation and optimal operation results of the circulating water system of the final power plant
